Application of Large-diameter Prestressed Anchors in a Deep Excavation Support
Deep excavation support is always been an important subject in construction engineering,di-rectly impacting the quality,social and economic benefits of a project.This paper uses the deep excava-tion support project of a high-rise building as a case study to illustrate the application of large-diameter prestressed anchors in the pile-anchor support design in Shijiazhuang City.Compared with the ordinary anchors,it can reduce the length of anchoring section,optimize the disadvantages of small force at the end of anchoring section,lower the difficulties of anchorage construction,and reduce project costs.This ap-proach provides a new design perspective for the application and popularization of pile-anchorage system structure.
